Several players in our app cannot purchase after upgrading iOS system. They make purchases every day before upgrading. After upgrading, they cannot purchase. User purchase behaviors: cannot request product: no callback received; didFailWithError received: Couldn’t communicate with a helper application . request product success: purchase stuck and after 2 mins failed with error message "There was a problem with your purchase" These players try to make purchases every day. Most of time they cannot get store products with no request callback. These player can make purchases in other apps. players' info: ipad7: 18.1.1 -> 18.2 ipad7: 18.1.1 -> 18.2.1 iPhone13 pro max: 17.6.1 -> 18.1.1 app info: xcode: 15.2 iap: store kit related code: iosIap.m (see the attachment) IOSIAP.m.txt Does any one know how to resolve this issue?
